GDI+ 对象释放崩溃的问题

确保在Gdiplus::GdiplusShutdown(m_gdiplusToken); 之前delete 掉GDI+的对象，例如：delete *pBitmap;

如果先Gdiplus::GdiplusShutdown(m_gdiplusToken);再delete *pBitmap; 程序会崩溃。

有时候会为了方便误将Gdiplus::GdiplusShutdown(m_gdiplusToken)先释放了，为了确保这种情况
在MFC中尽量按下面方式释放:
int CXXXApp:: ExitInitInstance()
{
GdiplusShutdown(m_GdiplusToken);
return CWinApp:: ExitInstance();

}

在WTL中释放：

GdiplusStartupInput   m_gdiplusStartupInput;ULONG_PTR             m_gdiplusToken;int WINAPI _tWinMain(HINSTANCE hInstance, HINSTANCE /*hPrevInstance*/, LPTSTR lpstrCmdLine, int nCmdShow){HRESULT hRes = ::CoInitialize(NULL);//HRESULT hRes = ::CoInitializeEx(NULL, COINIT_MULTITHREADED);ATLASSERT(SUCCEEDED(hRes));      Gdiplus::GdiplusStartup(&m_gdiplusToken, &m_gdiplusStartupInput, NULL);::DefWindowProc(NULL, 0, 0, 0L);AtlInitCommonControls(ICC_BAR_CLASSES);// add flags to support other controlshRes = _Module.Init(NULL, hInstance);ATLASSERT(SUCCEEDED(hRes));int nRet = Run(lpstrCmdLine, nCmdShow);_Module.Term();::CoUninitialize();    Gdiplus::GdiplusShutdown(m_gdiplusToken);return nRet;}
